TXB0108QPWRQ1 - 8-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXB0108QPWRQ1 is an automotive-qualified (AEC-Q100) 8-bit bidirectional voltage-level translator with auto-direction sensing and ±15kV ESD protection, packaged in a 20-pin TSSOP (PW). Port A supports 1.2V to 3.6V supplies while Port B supports 1.65V to 5.5V, enabling translation between any two logic rails in these ranges. A voltage-level translator (also called a logic level shifter) is an interface IC that enables digital devices operating on different supply rails - such as a 1.8V microcontroller and a 5V peripheral - to communicate reliably. Translators sit within the broader logic IC family, under interface and signal-conversion devices, and are essential wherever mixed-voltage systems coexist on one board. Key features include auto-direction sensing that eliminates the need for a direction-control pin, an output-enable (OE) input that places all I/O in Hi-Z when low, and ±15kV IEC ESD protection on I/O pins. The TXB0108-Q1 uses TI TXB-type push-pull architecture, delivering symmetric drive on both ports without external pull-up or pull-down resistors, and supports data rates up to 100 Mbps for 1.2V to 3.6V translation per the datasheet. The device operates from -40C to +125C (AEC-Q100 Grade 1), making it suitable for harsh automotive environments. Its TSSOP-20 package is standard, easy to assemble, and compatible with the commercial TXB0108PWR footprint for design reuse. Typical applications include automotive infotainment and cluster modules interfacing 3.3V MCUs with 5V sensors, mixed-voltage SPI/I2C-style GPIO expansion, industrial control modules, and portable mixed-signal systems bridging 1.8V and 5V rails. Design note: the TXB architecture has relatively weak output drive (not intended for bus-holding or heavy loads); avoid using it for I2C open-drain buses - the TXS family is a better fit. Pull OE low during power sequencing to prevent bus contention.
TXG4021-Q1 - ±40V 2-bit Ground-Level Translator | TI
The Texas Instruments TXG4021-Q1 is an automotive-grade, 2-bit, fixed-direction, non-galvanic ground-level translator supporting logic-level shifting between 1.71V and 5.5V and ground-level shifting up to ±40V, delivered in an 8-pin SOIC (D) package with a maximum data rate of 264 Mbps. A ground-level translator is a specialized type of voltage level shifter within the broader logic IC family. While standard level translators only shift logic thresholds between supply domains (for example 3.3V to 5V), a ground-level translator also bridges systems whose ground references differ by tens of volts - a common condition in automotive and industrial environments where load currents in shared returns lift local ground potentials. The TXG402x-Q1 family solves this without galvanic isolation, offering a lower-cost, smaller-footprint alternative to digital isolators where only ground-offset tolerance is needed. Key features include the ±40V ground-shift tolerance, the 1.71V to 5.5V logic-level range on both sides, a fixed (unidirectional) direction configuration with two channels in a 1/1 arrangement, and a 264 Mbps maximum data rate. The -Q1 variant is qualified for automotive applications per TI's automotive qualification flow, supporting AEC-oriented design flows. Architecturally, the device is non-galvanic: input and output stages share a common substrate reference topology that tolerates large ground differentials while translating logic swings, unlike optocoupler or transformer-based isolators. This yields lower propagation delay and lower cost than isolation approaches, with the trade-off that the ground offset is tolerated rather than fully isolated. Typical applications include automotive body electronics and lighting modules, motor-drive gate-drive interfaces where ground lift occurs, and industrial PLC I/O cards bridging a 1.71V-5.5V controller domain to a high-side domain with a shifted ground. Design consideration: because the part is unidirectional, confirm signal direction is fixed in your topology; it cannot be used for bidirectional buses such as I2C without external direction handling.

TXH0137D-Q1 - 7-Bit 30V Level Translator | Texas Instruments
The Texas Instruments TXH0137D-Q1 is an automotive-qualified 7-bit, single-supply, fixed-direction voltage-level translator with inverted open-drain outputs, housed in a 14-pin TSSOP (PW) package rated from -40C to +125C. A voltage-level translator is a type of logic IC that converts digital signals from one voltage domain to another, sitting within the broader hierarchy of logic ICs, interface ICs, and semiconductors. Level translators are essential whenever chips operating at different supply rails - for example a 3.3V microcontroller and a 12V industrial sensor - must exchange signals safely. Fixed-direction translators like this one assign a permanent direction to each channel, avoiding the overhead and ambiguity of direction-control pins. Key features include 7 translation channels in a single package, open-drain outputs that support voltages up to 30V, and output currents up to 100mA per channel. The inverted output polarity allows the device to double as a level-shifting buffer-inverter, and the open-drain structure lets designers pull outputs to any rail within the 30V rating. As a Q1 device, it carries TI's automotive qualification for -40C to +125C operation. On the technical side, because output currents of up to 100mA per channel are very high for a level translator, the outputs are more susceptible to large overshoot caused by reactive loads. To address this, the TXH0137D-Q1 integrates clamping overshoot-protection diodes on its outputs, improving robustness against inductive and capacitive ringing in automotive wiring environments. Additionally, the open-drain outputs can be tied (paralleling) together to achieve higher aggregate current capability, a flexibility not found in push-pull translators. Typical applications include automotive body electronics and gateways, level-shifting between low-voltage MCUs and high-voltage sensors or actuators, industrial PLC I/O modules, and driving relays, LEDs, or solenoids that require more than the few milliamps a standard logic gate can source. The 30V output rating and 100mA drive make it a direct fit for 12V and 24V automotive rail signaling. A key design consideration: with open-drain outputs, external pull-up resistors are required, and their value sets both the output high level and the rise time. Size pull-ups to balance current consumption against edge speed, and rely on the integrated clamp diodes for overshoot events rather than external TVS in most designs.

TXS0102DCUR - 2-Bit Bidirectional Level Shifter | Texas Instruments
The Texas Instruments TXS0102DCUR is a 2-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It enables digital switching compatibility between mixed-voltage systems using two separate configurable power-supply rails: the A ports support 1.65V to 3.6V while tracking VCCA, and the B ports support 2.3V to 5.5V while tracking VCCB. The device comes in an 8-pin VSSOP (DCU) package and operates from -40C to +85C. A voltage-level translator, also called a level shifter, is an integrated circuit that allows communication between components operating at different voltage levels. In mixed-voltage systems combining 3.3V microcontrollers with 5V sensors, or 1.8V logic with 3.3V peripherals, level shifters ensure logic high and low signals are correctly interpreted across voltage domains. The TXS0102 belongs to the bidirectional translator class, which shifts signals in both directions without a direction-control signal, simplifying design and reducing pin count within the broader logic IC and voltage-translation hierarchy. Key features include auto-direction sensing with no direction pin required, maximum data rates of 24 Mbps for push-pull and 2 Mbps for open-drain applications, and support for I2C, SMBus, and UART interfaces. A one-shot accelerator architecture speeds up rising edges even with capacitive loads. The OE pin, when low, places outputs in a high-impedance state for power sequencing and bus isolation. Technically, the TXS0102 uses a pass-gate architecture with integrated pull-up resistors on both A and B ports. When a line is driven low the pass-gate turns on; when released, internal pull-ups raise the line to the respective rail. This enables true bidirectional operation without external control. Typical applications include interfacing microcontrollers with sensors at different voltages, I2C and SMBus bus translation, and UART level shifting between 3.3V and 5V systems in consumer electronics, industrial control, and automotive infotainment. Design tip: ensure VCCA and VCCB stay within specified ranges, control the OE pin to avoid bus contention, and consider the 24 Mbps limit for high-speed links.
TXS0104EQPWRQ1 - 4-Bit Auto-Direction Level Translator | TI
The Texas Instruments TXS0104EQPWRQ1 is an automotive-grade, 4-bit bidirectional voltage-level translator supporting 24 Mbps data rates in a 14-pin TSSOP (PW) package, qualified to AEC-Q100 for -40C to +125C operation. A voltage-level translator (also called a level shifter) is a logic IC that interfaces digital signals between circuits operating at different supply voltages, for example bridging a 1.8V microcontroller to a 5V sensor bus. Translators sit within the broader voltage-translation family of logic ICs, alongside direction-controlled transceivers and unidirectional buffers. The TXS0104E-Q1 belongs to TI's auto-direction TXS family, which requires no host-side direction-control pin. Key features include auto-direction sensing that eliminates the DIR pin entirely, mixed open-drain and push-pull operation per channel, a wide VCCA range of 1.65V to 3.6V and VCCB range of 2.3V to 5.5V, and a 4 kbps to 24 Mbps data-rate window. An active-high OE pin places all I/O in high-impedance during power-up, enabling partial power-down sequencing. Architecturally, the TXS family uses a discrete integration approach with on-chip series resistors and one-shot edge accelerators: the resistors form a passive divider/clamp for open-drain buses while one-shots speed up rising edges for push-pull signals. This makes it tolerant of I2C, SMBus, SPI, UART and GPIO mixed-direction traffic but limits DC drive capability (typ. 2 mA sink at 3.3V side), which distinguishes it from the TXB push-pull-only family. Typical applications include I2C level shifting between 3.3V and 5V domains, automotive infotainment and body-control module GPIO expansion, and mixed-voltage UART/SD-card interfaces. AEC-Q100 qualification suits it for under-hood and cabin electronics. Design consideration: do not use the TXS family where channels source continuous DC current above 2-3 mA or where extremely low standby current is required; the always-on one-shot architecture draws current on every edge.

TXS0108EPWR - 8-Bit Bidirectional Level Shifter 60Mbps | TI
The Texas Instruments TXS0108EPWR is an 8-bit bidirectional voltage-level translator for open-drain and push-pull applications, housed in a 20-pin TSSOP (PW) package. It operates from two independently supplied rails, VCCA (1.2V to 3.6V on the A port) and VCCB (1.65V to 5.5V on the B port), with data rates up to 60 Mbps for push-pull signals and 2 Mbps for open-drain signals. A voltage-level translator, also called a level shifter, is an integrated circuit that enables digital communication between systems operating at different voltage domains. Within the logic-translation hierarchy, bidirectional auto-direction translators such as the TXS0108E sit alongside direction-controlled families like the SN74LVC8T245 and TXB0108, providing mixed-voltage interfacing for microcontrollers, peripherals, and buses. Key features include automatic direction sensing, which eliminates a direction-control pin, and a VCC isolation feature: if either supply rail is at GND, all I/Os enter high impedance, preventing back-powering during partial power-down. Quiescent current is low at 620 uA, and the one-shot accelerator architecture speeds low-to-high transitions for high-speed push-pull operation. The device is specified from -40C to +85C, is RoHS compliant, and carries MSL 1 (260C unlimited floor life). Architecturally, the TXS0108E combines a pull-up based open-drain translation path with edge-accelerating one-shots, making it equally suitable for I2C-style open-drain buses and push-pull SPI/UART links. This auto-direction design trades output drive strength for bidirectionality, so it excels on lightly loaded point-to-point links rather than heavily bused systems. Typical applications include interfacing 1.8V or 3.3V microcontrollers with 5V sensors, SD/MMC memory-card interfaces, UART/SPI/I2C bus translation, and mixed-voltage communication in consumer, industrial, and IoT systems. Design tip: for open-drain use, external pull-up resistors are required on both sides; keep them sized per datasheet recommendations to avoid rise-time degradation at target data rates. Pricing as of 2026-08-29.
TXS0108ERGYR - 8-Bit Bidirectional Level Shifter | Texas Instruments
The Texas Instruments TXS0108ERGYR is an 8-bit bidirectional voltage-level translator designed for open-drain and push-pull applications. It operates with a VCCA range of 1.4V to 3.6V and a VCCB range of 1.65V to 5.5V (with VCCA <= VCCB), supporting maximum data rates of 110Mbps for push-pull signals and 1.2Mbps for open-drain buses. The device comes in a 20-pin VQFN (RGY) package measuring 3.5x4.5mm with an operating temperature range of -40C to +85C. A voltage-level translator, also called a level shifter, is a logic IC that enables communication between devices operating at different supply voltages, such as a 1.8V microcontroller interfacing with a 5V peripheral. Level translators sit within the broader logic IC family and are essential in any mixed-voltage embedded system. The TXS0108E requires no direction-control signal because its auto-direction sensing architecture detects data flow automatically, reducing MCU pin usage and firmware complexity. Key features include VCC isolation, which places all outputs in high-impedance if either supply is at GND; no power-supply sequencing requirement, since either VCCA or VCCB can ramp first; and a one-shot edge-rate accelerator that boosts rise times to achieve the 110Mbps push-pull data rate. The transistor-based pass-gate architecture supports both open-drain buses such as I2C and push-pull interfaces such as SPI and UART without configuration. Typical applications include I2C, SPI, and UART level shifting between low-voltage MCUs (1.8V/2.5V/3.3V) and 5V peripherals, SD card and SIM card interfaces, and general-purpose GPIO translation in industrial and consumer systems. As of 2026-08-30, pricing starts at approximately $0.60-$0.90 at 1-piece quantity from authorized distributors. Design tip: always keep VCCA <= VCCB, place 0.1uF and 10uF decoupling capacitors close to both supply pins, and use external pull-up resistors on both sides for open-drain operation.
and - Logic AND Gate IC | Digital Logic IC | Search Guide
The component identifier "and" is a generic reserved English word that appears in thousands of electronic component search queries, but it is not a valid standalone manufacturer part number (MPN). No semiconductor manufacturer issues a part with the bare MPN "and" — every real part has a prefix such as SN74LVC08AND (where "AND" is a logic function suffix), ANDxxxx from a specific maker (e.g. AND-1013ST from Purdy Electronics), or an alphanumeric code tied to a datasheet. Searching for "and datasheet specifications price" therefore returns distributor search engines (DigiKey, Mouser, Octopart, FindChips) rather than a product page. Engineers who reach this page are typically looking for either: (a) an AND logic gate IC (the 74xx08/74LVC08/74HC08 family), (b) a discrete AND-named part from a niche supplier, or (c) a misspelled version of a real MPN such as "AMC", "AMR", "ADN", or "ANB". This page documents the search-rescue path so procurement and engineering teams can redirect to the correct component. Background: An AND gate is a fundamental digital logic primitive. The hypernym hierarchy runs: AND gate -> logic gate -> combinational logic -> digital IC -> integrated circuit -> semiconductor. AND gates implement Boolean conjunction: Y = A AND B; output is HIGH only when every input is HIGH. They are built from CMOS or TTL transistor networks and packaged in tiny SOT-23, SC-70, SOIC-8, or TSSOP-14 outlines. Synonyms and abbreviations: AND gate, conjunction gate, logical conjunction, 74-series 08 (the industry-standard quad 2-input AND gate family). Key features of the canonical quad 2-input AND gate (e.g. SN74LVC08A) include: 4 independent 2-input AND gates in one package, 1.65 V to 5.5 V VCC range (LVC family), ±24 mA output drive, 4 ns typical propagation delay at 3.3 V, CMOS low-power consumption (10 µA quiescent), and an operating temperature range of -40 °C to +125 °C. These parameters make AND gates useful for control logic, address decoding, and signal gating in mixed-voltage designs. Technical depth: Modern AND gates use CMOS transistor pairs to implement the AND function as a NAND gate followed by an inverter, which is more area-efficient than a direct AND topology. The LVC (Low-Voltage CMOS) family is optimized for 3.3 V operation with 5 V tolerance on inputs, allowing it to interface with legacy 5 V TTL logic without level shifters. Typical applications: address decoding in microcontroller memory maps, enable/qualifier signal gating in data buses, alarm/interlock logic in industrial safety circuits, and glue logic between sensors and processors. Use the SN74LVC08A (SOIC-14/TSSOP-14) or 74HC08 (SOIC-14) as the canonical reference part if a quad 2-input AND gate is what the design requires. Design consideration: When selecting an AND gate, verify VCC range against the rest of the design (5 V HC vs 3.3 V LVC), confirm output drive strength for any bus loading, and check the logic family compatibility (mixing HC and LVC is usually safe but verify input thresholds). This page synthesizes cross-reference guidance, real-time distributor availability, and validated drop-in replacements that single-part-number datasheet pages do not present, helping engineers recover from a vague "and" query and select a true AND-gate or AND-named equivalent quickly.
